ZONE! 951,16.- lbtmwg Patented July 12, 1932 UNITED STATES PATENT OFFICE JOHN IBD YDEN PEIBCE, OF NEW YORK, N. Y., ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE TABUILATING MACHINE COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY PRINTING MECHANISM Application filed April 9,

This invention relates to tabulating machines and more particularly to improvements in the printing mechanisms therefor.

Tabulating machines, as presently developed, are provided with printing mechanisms whereby numerals represented by mdex point perforations may be indicated by printing upon a record strip, and, in addition thereto, such printing mechanisms are also employed to represent the result of some computation, such as a total of a series of items. It frequently happens that it is desirable to identify the printed items or computations by printed words, abbreviations or the'like, and in some instances this can readily be accomplished by substituting letter type for the numeral bearing type so that the index points will represent alphabetical or other characters. Due to the limitations in the number of index points in a card column, which is usually ten, a limited number of characters may be printed detracting from the usefulness of such an expedient.

It is then the main object of the present invention to extend the usefulness of such printing mechanisms whereby they maybe called upon when occasion requires to print either numerals, or substantially all of the alphabetical characters and under control of a single card column.

It is a further object to provide an improved mechanism designed to be controlled by a single card column which may print either alphabetical or numeral characters arranged in groups, which characters are far in excess of the number of index points in a card column.

It is a further object of the invention to devise an improved means whereby characters in certain groups may be selected by perforations in a particular field of the card.

Another object of the invention is to, devise means whereby the perforations of the record card may be analyzed by sensing pins and the reading taken by the pins converted by electrical devices which in turn control the type selecting mechanism.

Another object is to devise means whereby the perforation sensing pins will effect a setting of brushes with respect" to their com- 1930. Serial No. 442,780.

mutators to control the timing of the electric circuits for controlling the operation of the type selecting mechanism.

In the present invention, type bars are used operating synchronously with commutators which in turn control electric circuits to energize the type selecting magnets at different times during the cycle of operation, depending upon the particular character to be printed from the type bar. The time in the cycle when the circuit will be established through the commutators to the selecting magnets depends upon the position of the brushes with respect to the commutators, which in turn are controlled by the sensing pins. Instead of using ten hole positions in a column to represent a digit, but four positions are used and for representing letters of the alphabet and other characters, six positions are used and instead of reading the card while it is moving past brushes, it is stopped I in a sensing position and pins are projected against the card to sense the perforations therein. One or more perforations in the six index point positions used may represent any given digit or letter in accordance with the well known Peirce combinational hole system which is illustrated in Fig. 15. Herein the six index point positions are labelled for convenience as 1, 2, A, B, C, D. The entire number ofcombinational perforations used is divided into four zones as indicated and the perforations in the index positions 1 and 2 determine to which zone a particular letter has been allotted.

Thus where no perforation occurs in either position 1 or 2, the character belongs to zone 1. Where there is a perforation in position 2, it belongs to the second zone. Where there is a perforation in osition 1, the character belongs to the t ird zone; and

where there are perforations in both the first and second positions, it indicates that the character belongs in the fourth zone. The type bar which is to be positioned under control of the various combinational hole perforations has type thereon which are arranged in zones (see Fig. 10) in the same order as in Fig. 15. The analyzing mechanism of the machine is adapted to determine from r the perforations in the first and second positions the zone from which printing isto take place and the analyzing mechanism cooperating with the positions A, B, C, D. will effect the selection of the particular character from that zone.

Type bar makam'sm tion 21 with an arm 22 secured to one end,

of a shaft 23. The shaft 23 has secured thereto arms 24 which carry a cross bar 25 to which are secured the upper ends of springs 26, the lower ends of which are individually connected to levers 27 which through links 28 pivoted to their free ends connect with the type bars 29. Clockwise rocking of the shaft 23 through the mechanism just traced will cause the rocking of the levers- 27 in the same direction under the influence of their s rings 26 to raise their corresponding type ars 29. The type bars are provided with ratchet-shaped teeth 30 which cooperate with stop pawls 31, one of lwhich is disposed in the plane of each type A magnet 32 associated with each column of the type bars is adapted upon energization to trip the stop pawl 31 into engagement with the teeth 30. The time of energization of magnets 32 is such as to trip the pawl 31 at the time when the particular character to be printed from the bar is opposite the printing position of the platen 33. Continued rotation of the shaft 23 after such interruption of the type, bar will cause springs 26 to stretch. At the end of the clockwise stroke of the shaft 23, hammers 34 are adapted to be tripped to impel the selected type against the platen 33 to print upon the record, thereon. Upon the return movement of shaft 23 a bail 36 connected by links 35 to arms 24 is adapted to engage the upper edges of the levers 27 to move the type bars 29 to their lower or restored position of Fig. 1.

The shaft 13 is connected by gearing 37 to a shaft 38 which in turn through a gear 39 secured thereto drives a gear 40 (see also Fig. 2). The shaft 38 and gears39 and 40 drive the card analyzing mechanism in synchronism with the type bar mechanism just described.

Gard feed mechanism lowermost card of the stack and advance it through the slot. The picker is mounted on sliding member 54 carried in the grooves 55- in the frame of the machine. The supporting member 54 is'provided with rack teeth meshing with a segmental gear 56 mounted on a shaft 57 and adapted to oscillate to move the picker back and forth. The shaft 57 has fixed thereon outside of the supporting plates 52 (Fig. 2) an arm 58 connected by a link 59 to a bell crank 60 pivoted at 61' and provided with cam. follower rollers cooperating with a pair of complementary cams 62 fixed on shaft 63. The shaft '63 has a clutch connected with a gear 64 to which it is normally connected and which for the purposes of this application maybe considered as being a rigid connection.

A magnet 65 is adapted to maintain this clutch connection during the operation of the machine and for this purpose is in a state of continued energization. The gear 64 meshes with a gear 66' which in turn meshes with gear 67. Gear 67 meshes with gear 68 which is driven by the gear 40.

One complete cycle of the shaft 63 causes the card picker to move once to the right to feed a card through the slot and back to the left as in Fig. 4. When the card is advanced from the bottom of the stack it is gripped between feed rollers 69 and fedv by these rollers to the next set of feed rollers 70 which in turn feed it between the plates 71, 72. The card is fed downwardly until it is stopped by a gate 73 rnounted on an arm 74 pivoted at 75. Fixed on shaft 75 (as shown in Fig. 2) is an arm 76 connected by link 77 to a cam follower arm 78 having a cam follower roller cooperating with a cam 79 on the shaft 63. A suitable spring holds the follower against its cam. The cam 79 is adapted to cause the gate 73 to move into the path of the card to stop it between the plates 71 and 72 and to rock counterclockwise to permit the card to pass out from between the plates later in the cycle. At this time the feed rollers 80 (Fig. 4) will feed the card out from between the plates. 71 and 72. A curved guide plate will guide the leading edge of the card into cooperation with the clips of a rotary card stacker 81 pivoted at 82. Thisstacker is well known in. the art and need not be described in detail. The stacker is actuated by a bevel pinion 83 (Fig. 2) on shaft 82 which has bevel gear connection as shown in this figure, to abevel gear 84 integral with the gear 66. The timing of the stacker is such that the clips are open to receive the card as it feeds downwardly over the guide plate. The clips then grip the card and pull it into the discharge stack or pocket 85. The turning of the feed rollers is effected by a gear 86 mounted on shaft 63 which meshes with pinion gears connected to the various roller shafts as shgwn in Fig. 2.

driven but is driven by being pressed against the card and in turn pressing the card against the outer roller 80 which is positively driven. The former roller is carried on an arm which is loose on shaft75 and which is provided with a pin which is-engaged by an arm 87 which is fixed on shaft 75. A suitable spring attached to the lower end of the roller arm tends to rock the roller against the card lightly. When the shaft 75 rocks to move the gate 73 to permit the card to be fed out, the arm 87 engages the arm carrying the in- Her roll r 80 and presses the roller firmly against he card to insure feeding thereof.

0am? analyzing mechanism After the card 50 has been fed to the sensing position between the plates 71, 72 and stopped by the gate 73, the'sensing pins 90 of which there are four for each column of data on the card, together with pins 90m and 90y are permitted to advance against the spring 93 thus tends to press the pin against the card or through the card if there is a perforation therein at that position. A restoring plate 94 resting against the collar fixed to the pins is adapted to restore the sensing pins to non-reading position as in Fig. 4 and to be moved to the left to permit the pins to take a reading from the card. The restoring plate 94 is connected to links 95 which are in turn connected to arms 96 fixed on a shaft 97 which as shown-in Fig. 2 has connected thereto an arm 98 connected by a link 99 to a cam follower. lever 100 pivoted at 101 and provided with a cam follower-roller cooperating with a cam 102 secured upon the shaft 38 (see also Fig. 1). A spring 103 con-. nected to one arm of the lever 100 holds the follower against the cam 102. The cam positively restores the'plate 94 to the position of Fig. 4 removing the pins from reading position while the spring 103 moves the plate 94 to the leftto permit the pins to be actuated by their springs 93 to take their readin s'.

The lowermost sensing pin 90 has xed thereon a block 104 having a pin 105 (see also Fig. 5) adapted to engage an arm 106d pivoted at 107 on a fixed support. Arm 108d pivoted on the arm 106d carries a brush 109d adapted to engage a commutator 110. The brushes 109d are held properly spaced by a slotted plate. The second pin 90, counting from the bottom, also has a block 104 cooperating with an arm 1060 flan card and has rocked its arm 106a and has advanced its brush 109a along the periphery of the commutator 111 from the dotted'line position to the full line position. The remairing pins have not found perforations in the card and have been stopped by the card and therefore have not changed the positionsof their brushes with respect to the commutators. Associated with the arms 106 are latching members 112 pivoted at 113 (see Fig. 3). Arms 114 connected to the latch members 112 are all connected to link 115 which is actuated by a latch 116 pivoted to bell crank follower arm 117 eooperating with a cam 118 on shaft 119. In Fig. 2 the shaft 119 has a gear 120 secured thereto, meshing with a gear 121 integral with the gear 68 so that the cam 118 makes a revolution for each revolution of the gear 68. After the sensing pins 90 have taken their readings and rocked their arms 1.06, the .cam'118 through the latch 116 engaging a projection 122' on link115, rocks the link to the left as viewed in Fig. 3 rocking all the arms 1142 and thereby rocking all of the latches'112 slightly counterclockwise as viewed in Fig. 5 to release all of thearms 106 so that they may shift under control of 1 the perforations in the card. Immediate-1y after this shifting the latches 112 can return to their operative position wherein they will latch all the arms 106 that have 'moved in such position as shown in Fig. 5 so that the pins 90 may then be restored, and the card fed from the sensing position.

VVhilethe arms 106 are'thus latched the reading is analyzed by the rotation of commutators 110, 111. The commutators are turning constantly and during the card feeding and analyzing portions of the-cycle the contacts 123 (see Fig. 17 are open.

These contacts are controlled by a cam 12% which may be mounted on any of theshafts, as for instance, shaft 119 which turns one revolution for each card cycle of the machine. After the reading has been taken and the arms 106 set, cam'124; releases the cont acts 123 and permits them to close. The commutators 110 are carried on a shaft 125 and the commutators 111 are carried on a shaft 126 which in Fig. 2 carry at their extremities pinions 127 and 128 respec tively. rPinion 127 meshes with the large gear 67 and the pinion 128 meshes with gear 68 throughan idler 129. The relative proportions of the gears are'such that the gears .125 and 126 make four revolutions for each cycle of the machine. /The first two revolutions-of the commutator are made in synchronism with the-rise of the type bar 29 in Fig. 1, and the remaining two'are made while the type bar is being restored. Fig. 16 shows a development of one'of the commutators 110 and one of the commutators 111. The shaded areas represent insulating material and the white areas represent conductor segments and sections between the segments (see also Fig. 13), wherein is showna detail sectional elevation of one of the commutators 110. All ofthe segments 132 on the lower edge of the commutator 111 are interconnected by a common. circumferential strip 133 while all of the segments 132 on the upper edge are connected by a'strip 13.4.. As shown in Fig. 16 the brushes 109a and 1097) are connected to each other by a wire 135. When .the pins 90 take a reading in accordance with the perforations corresponding to the numeral 6 and set their commutator brushes accordingly, and when the commutators have turned through the 9, 8 and 7 positions to the 6 position, the parts will be in the relative positions as shown.

Here it will be seen that presuming the current to be entering through the brush 109d, it will pass into segment 132, along the connected strip 133 to the segment 132 which is now in connection with the brush 1096. From here the current passes through wire 135 to brush 109a into the segment 132 along the connecting member 134 to the segment 132 with which the brush 1090 is now in contact. Thus after the brushes have been set and the commutators 110, 111 continue to tate, when they reach the sixth position, current will pass through the commutator brushes to complete a circuit through the printing magnet 32 to interrupt the type bar in the sixth position.

Z one selecting mechanism Referring to Fig. 15 the arrangement of the perforations is such that for each arrangement of the perforations of the index points A, B, C, D, there are allotted four characters, one for each of the zones. For instance, in

zone 1, the numeral 6 is represented by a perforation at A and D: in zone 2, the letter B is also represented by .a perforation at A and D; in zone 3, the letter P is similarly represented; and again in zone 4, the letter X.

Thus it will be seen that for each. of the comcuits at a time when the corresponding characters are 0 posite the printing line of the platen. In Fig. 11 is shown dia rammatical- 1y 2. continuous development 0 the commutators 110, 111 for the duration of four revolu tions. Superimposed on these developments are the brushes 109a, 1096, 1090, 109d, shifted under control of the perforations in the positions A and D as in Fig. 16. The various positions in which circuits may be completed have been shown and an inspection ofthe figure will disclose that when the numeral 6 in zone 1 is on the printing line, a circuit will be established as described in connection with Fig. 15. I

Continued rotation of the commutators will bring the segments into such relation with the brushes that a circuit will be estab lished in zone 2 in the B position. During the second revolution of the commutators 110,

111, these two circuits will be repeated in the P position of zone 3 and the X position of zone 4.

Which of these circuits is to be effected to position the type bar is determined by the two uppermost sensing pins 90% and 90y. In Fig. 5 pin 90y is provided with a stop collar 136 secured thereto which cooperates with the frame 92 to limit the movement of the pin. At its rear end it carries a block 137 having a. projection 138 disposed in the path of a block 139, secured to the end of pin 90m. The pins in the extremities of the blocks 137 and 139 cooperate with a spring pressed latch .140 which cooperates with the stops of a zone selector 141 which is spring biased upwardly. The selector 141 carries an insulated slider 142 cooperating on one side with conducting bars 143, 144, 145,146 and with a strip 147. The members141' are controlled by a bar 148 connected at its ends to arms 149 secured to card. the bar 148' is elevated to release the members 141 so they may take a position according to the arrangement of perforations in the index positions 1 and 2 of the card. If neither of the pins 90m. 901 advance, the member 141 will remain in the position 'of Fig. 5 wherein the slider 142'lies adjacent to bar 143. If the pin 902 alone advances, as in Fig. 7 it will move a distance limited by the cooperation of block 136 with the frame 92 and will rock the latch 140into a position where it will intercept the member 141 in a position where slider 142 lies adjacent to in Fig. 8 the advancement of pin 90a: alone will permit the pin to advance untilits block 139 engages the projection 138 on the block" 137, this movementbeing suflicient to displace the latch 140 so that it will engage the member 141 to hold the slider 142 in cooperation with the bar 145. [If both pins advance, the member 141 will'be permitted to move to the position of Fig. 9. wherein slider 142 makesv contact with the bar 146. A zone set up having thus been effected by the pins 90w, 90fy, they may be returned together with the pins 90 without disturbing the set up of members 141. Referring to the wiring diagram of Fig. 17 the contact blocks 147 are individually connected to the brushes 1091i and the brushes 1090 terminate at individual plugs 155. The

contact bars 143, 144, 145, 146, are connected to brushes 143a,-144a, 145a, 146a,which cooperate with a commutator 156 which in Fig. 3 is shown as being secured to the extremity of shaft 153. The commutator 156 is provided with a conducting segment 157 which successively cooperates with the brushes 143a,

144a, 145a, 146a to connect the brushes to a common ring 158 (see Fig. 14) which through a brush 159 is connected to one side ofthe source of current 160 through contact 123 and card lever contact 161. The commutator 156 makes one revolution for each card cycle of the machine and the timing is such that as the type positions of the type bar (see Fig. 10) included in zone 1 successlvely approach the printing line, the segment 157 is in cooperation with the brush 143a. As the type included in zone 2 of the type barapproach the printing line, the segment cooperates with the brush 144a and thereafter as zone 3 passes the printing line, the segment is in cooperation with the brush 145a and similarly the segment contacts with brush 146a while zone 4 cooperates with the printing line.

In Fig. 3 the shaft 97 which as has heretofore been pointed out rocks in a clockwise direction upon advance of the sensing pins, carries an arm 171 which has pin and slot connection to a link 172. The other endof the link is pivoted to an arm of a bell crank 173 upon whose other arm is pivoted the interposer 170. The pin and slot connection between the link 17.0 and arm 171 is such that duringthe beginning of the clockwise movement of arm 171 the pins 90 and pin 165 are permitted to advance to sense the card. If during this time the pin 165 is blocked by a card, interposer 170 is positioned beneath the projection 164a. Toward the end of the clockwise movement of arm 171', it will cause movement of link 172 and therethrough rock the bell crank 17 3 in a counterclockwise direction to the position of Fig. 3a wherein the 'interposer 170 has been moved up.- wardly to close the contact 161. Had there been no card in sensing position between the plates 71 and 72, the further advance of pin 165 through plate 71 would have located the interposer in its dotted line position of Fig. 3a and the subsequent rocking of bell crank 173 would not have affected contact 161. The bell crank 173 cooperates with a pin 174 on a spring pressed latch 17 5 in such manner that as the bell crank returns to its normal position by moving in a clockwise directioh'the latch 175 will move beneath a projection 1646 of the arm 164 to latch the contact 161 in a closed position. With the above construction the successive presentation of cards to the sensing pins will permit the continued closure of contact 161. Upon failure of a card to register with the pin 165, the latch 175 will be tripped by bell crank 173 and the contact 161 will open before the commutator readingdevices have operated and no circuits will be established to the type bar magnets.

In Fig. 3 the latch 116 which cooperates with the link 115 is connected by a link 176 to an arm 177 pivoted at 178 which in turn has link connection to a bell crank 17 9 connected by a link 180 to a pivoted lever 181. The picker shaft 57 carries an arm 182 which has a by-pass 183 pivoted at its free end and which is adapted to cooperate with a camming projection 181a of lever 181.

The sliders 142 are adapted to make electrical connection between their individual strips 147 and one of the bars 143-146 so that as in the wiring diagram of Fig. 17 when the first slider to the left is cooperating with the bar 143 of zone 1, the particular set up of the brushes 109(1-109d will be effective to select the corresponding type element in the first zone only. With the same arrangement of the brushes 109a109d and the slider cooperating with the bar 144 of zone 2, the circuit through the commutators 110, 111 would be ineffective during the passage of corresponding typein zone 1 past the printing line and the appropriate character in the second zone would be selected for printing.

From the foregoing it will be apparent that for any particular combinational setting of the brushes 109a109d there will be four possible timed circuit impulses through the commutators 110, 111. The particular circuit to be permitted to function will depend upon the coding perforation in the index positionsl and 2 on the card so that but one of the possible circuits will be selected. The printing magnets 32 are connected to plugs 162 which may be connected by suitable plug wires to the plugs 155 and also to the opposite side of line 163.

Gard lever contact The card lever contacts 161 (see also Fig. 3) has its lower blade abutting an arm 164 pivoted at one end. A special card sensing pin 165 is adapted to advance with the pins 90.

This special pin 165 is located so as to cooperate, with a portion of the card in which no code perforations are to appear. It is supported at one, end by the restoring bar 94 and at its other by the fixed plate 92 (see Fig. 3a) A block 165a attached at an intermediate point of the pin has pin and slot connection with an arm 166 secured to a rod 167 which extends to the outside of the frame 52 where it carries a spring pressed arm 168' which in turn through a link 169 is adapted to rock an interposer 170. If upon advance of. the bar 94 the pin 165 is stopped by the presence of the card 50, the slight movement of the pin 165 through the linkage described will permit the interposer 170 to move to the position of Fig. 3a where its free end lies under a projection 164a of the pivoted member 164.

The arm 182 and its by-pass 183 are normally located with the machine at rest in the position shown. During the first cycle of operations the arm 171 is latched as shown which has the effect of locking the pins in their retracted position while the first card is fed from the hopper 51 to the sensing station. The counterclockwise rotation of the picker shaft 57 moves the by-pass 183 past the camming projection 181a without afiecting its position. Upon the return movement of by-pass 183 it will strike the camming pro j ection and rock the lever 181 to the left thus raising the arm 177 out of engagement with arm 1(1 and also raising the latch 116 into cooperation with the projection 122 on the link 115. This releases the arm 171 for operation in the subsequent cycle and during such operation the upper end of the arm cooperates with an arcuate portion of the arm 177 to maintain it in its displaced position and also to hold the latch 116 in'its operative position. Thus each cycle of operationsthe arm 171 is latched and again unlatched by the 7 Reoapc'tulatz'on Briefly reviewing the operation of the device, cards 50 are placed in the feed hopper 51 and the lowermost one is fed to the analyzing position where it is held by the stopping gate 73. The analyzing pins 90, 9009, 901 then advance against the card to read the perforations thereon carrying With them the commutator brushes 109a109d which take a setting in accordance with the combinational arrangement of the perforations in the various columns. The brushes are then looked in position by the rotary locking latches 112 and the sensing pins are restored so that the card may be advanced to the discharge stack 85. Simultaneously with the settlng of the brushes the zone selecting sliders 142 are also positioned and this positioning is maintained together with the displaced brush set up.

The type bars 29 will now rise in synchronism with the rotation of the commutators, the first zone of the type bar passing the printing position during the first half revo- 'lution of the commutator, the second zone passing the printing position during the second half revolution of the commutators, andthe third and fourth zones of the type bar cooperating with the printing position during the second revolution of the commutators. After the type bars have all been thus positioned, the printing hammers 34 are tripped and an impression is made on the record sheet in accordance with the setting of the type bars. The type bars are then restored and the zone selecting sliders 142 are also'returned to normal position while a new card I is fed to analyzing position and the cycle of operations is repeated. I
